By studying theηc exclusive decay to double glueballs,we introduce a model to phenomenologically mimic the gluon-pair-vacuum interaction vertices,namely the 0^++*** on this model,we study glueball production in pseudoscalar quarkonium decays,explicitlyηc→f0(1500)η(1405),ηb→f0(1500)η(1405),andηb→f0(1710)η(1405)*** them f0(1500)and f0(1710)are well-known scalars possessing large glue components,whileη(1405)is a potential candidate for a pseudoscalar *** preliminary calculation results indicate that these processes are marginally accessible in the presently running experiments BES III,BELLE II,and LHCb.

For the first time,we have introduced the tetrahedron constellation of gravitational wave observatory (TEGO) composed of four identical spacecrafts (S/Cs).The laser telescopes and their pointing structures are mounted on the S/C platform and are evenly distributed at three locations 120 degrees *** structures form automatically a stable mass center for the *** time delay interferometry (TDI) is used to suppress the frequency noise of gravitational wave (GW) *** unequal-arm Michelson TDI configuration and the Sagnac TDI configuration are equally effective at eliminating the laser frequency noise based on the TEGO ***,compared with the configurations of LISA,Taiji,and TianQin,the TEGO has more combinations of optical paths in its TDI system sensitive to GW *** six arms of TEGO are simultaneously sensitive to the six polarization modes of *** sensitivity implies that GW modes beyond the predictions of general relativity (GR)can be detected *** instance,a scalar longitudinal mode of GWs,which is not predicted by GR,has been identified as a dominant polarization *** mode is found to be evident in the response amplitudes of the TEGO arms,such as between S/C1 and S/C4,and S/C3 and S/C4,at certain orbital positions.

Based on the resource theory for quantifying the coherence of quantum channels, we introduce a new coherence quantifier for quantum channels via maximum relative entropy. We prove that the maximum relative entropy for coherence of quantum channels is directly related to the maximally coherent channels under a particular class of superoperations, which results in an operational interpretation of the maximum relative entropy for coherence of quantum channels. We also introduce the conception of subsuperchannels and sub-superchannel discrimination. For any quantum channels, we show that the advantage of quantum channels in sub-superchannel discrimination can be exactly characterized by the maximum relative entropy of coherence for quantum channels. Similar to the maximum relative entropy of coherence for channels, the robustness of coherence for quantum channels has also been investigated. We show that the maximum relative entropy of coherence for channels provides new operational interpretations of robustness of coherence for quantum channels and illustrates the equivalence of the dephasing-covariant superchannels,incoherent superchannels, and strictly incoherent superchannels in these two operational tasks.

Lepton number violation processes can be induced by the Majorana neutrino exchange, which provide evidence for the Majorana nature of neutrinos. In addition to the natural explanation of the small neutrino masses,Type-I seesaw mechanism predicts the existence of Majorana neutrinos. The aim of this work is to study the B meson rare decays B^+→K^((*))+μ^+μ^-in the Standard Model and its extensions, and then to investigate the same-sign decay process B^+→K^((*)-)μ^+μ^+. The corresponding dilepton invariant mass distributions are calculated. It is found that the dilepton angular distributions could shed light on the properties of new interactions induced by Majorana neutrinos.
